I am sensing that she probably has a (temporary) state of mental unwellness that is considered sufficient for her to not be of her usual sound mind. That in an ideal world she would need supervision and / or hospitalisation and maybe medicating until she's stable - unfortunately we live in a world where people can be that profoundly unwell but not get the right help they need. If they go wandering in that state or get a bee in their bonnet, then they are at very high risk of coming to harm or harming themselves when not in their right mind, doing things they would never normally do. Were that to be the case, then it means that legally she is not culpable for her own actions and is at the highest level of risk.
Sadly, I think there are a few people here who will know what I'm talking about here if they have a loved one who has episodes of certain types of illness.
This is just my speculation, the has been nothing in the MSM to openly state this case and it has only been alluded to.
